MEANS FOR FORMING ANNOUNCEMENTS 0N GLASS WINDOWS AND OTHER PLANE SURFACES.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed April 21, 1906. Serial No. 318,026

To all whom it may concern:

Be it known that I, ERNEST GEORGE MrToHELL, a subject of the King of Great Britain, residing in Bowden, in the county of Chester, in the Kingdom of England, chemist, have invented certain new and useful Improvements in Means for Forming Announcements on Glass Windows and other Plane Surfaces, for which application has been made in Great Britain, No. 9,242, dated May 2, 1905.

This invention has for its object an ar rangement whereby paper, celluloid, papiermach, and other like letters can be applied to glass windows, boards, and other structures rapidly and effectively and without skilled labor, so as to produce a neat-looking advertisement or announcement.

In the accompanying drawings, Figure 1. is an elevation of letters made in accordance with the present invention. Fig. 2 is a side view, and Fig. 3 a detail, of a spacing-piece.

The invention consists, essentially, in stamping the letters out of the cardboard, paper, or other material which has been gummed on one side, but leaving, as shown in the accompanying drawing, either on each side of the bottom or on each side of the bottom and top, a little strip or spacingpiece a of the material beyond the letter, so as to show the exact rectangle occupied by the letter and half the spacing between the letters. The rectangle for the letter S is indicated by the dashanddot lines C, D, and E and the base of the letter, and for theletter L by the lines E, G, and F and the base of the letter L from the line E to F. The lines C, E, and F are at the respective extreme limits of the spacing-pieces, and the lines D and G are along the tops of the letters S and L respectively.

This extra little piece has preferably weakened lines, nicked or perforated, as at a, so that it can easily be broken or torn off, and has a resist I), such as tinfoil or other material, placed over the gum on it. The result is when a series of these letters each having the corners of a square are placed in a row they can be lined to a given line and be accurately spaced by simply being pressed up together. The gum can be moistened, and thus the letters stuck to the glass or board, and then when these have dried the squaring-pieces a at the corners can be torn or broken off or cut off with a sharp knife, and thus a clearly-defined letter remains fixed to the glass. These letters can be sent out in various sizes, various colors, and any required shape, and they can not merely be gummed, but they can have attached to them adhesive cements, insoluble in water, but soluble in some other liquidsuch, for instance, as spirits of wine or benzol. In that case the letters can be simply wet with benzol or spirits of wine instead of with water when being placed in position. If the outer surface of the letters be waterproofed with a little celluloid solution, india-rubber solution, or the like, they will stand very permanently on a glass window when fixed with pyroxylin solution or other solution as de scribed to be insoluble in rain-water. Strips c, Fig. 3, of ungummed paper moistened are placed between letters where wider spacing is required and removed after the lettering is complete.

I declare that what I claim is 1. In means for forming announcements on glass windows and other plane surfaces, letters adapted to form the announcement, and small strips or spacing-pieces connected to the same, said strips or spacing-pieces be ing of such a size as to indicate the exact rectangle occupied by the letter and half the spacing between the letters, and an adhesive layer on the back of said letters.

2. In means for forming announcements on glass windows and other plane surfaces, letters adapted to form the announcement, and small strips or spacing-pieces connected to the same, said strips or spacing-pieces being of such a size as to indicate the exact rectangle occupied by the letter and half the spacing between the letters, an adhesive layer on the back of said letters, and a resist on the back of said strips.

3. In means for forming announcements on glass windows and other plane surfaces, letters adapted to form the announcement, and small strips or spacing-pieces connected to the same, said strips or spacing-pieces being of such a size as to indicate the exact rectangle occupied by the letter and half the spacing between the letters, said strips having weakened lines so as to be easily removed.

4. In means for forming announcements on glass windows and other plane surfaces, letters adapted to form the announcement, and small strips or spacing-pieces connected to the same, said strips or spacing-pieces being of such a size as to indicate the exact rectangle occupied by the letter and half the spacing between the letters, said strips having weakened lines so as to be easily removed, adhesive means on the back of said letters and strips, and a resist on said strips.

5. In means for forming announcements on glass Windows and other plane surfaces,

letters adapted to form the announcement,

and small strips or spacing-pieces connected to the same, said strips or spacing-pieces be ing of such a size as to indicate the exact rectangle occupied by the letter and half the spacing between the letters, in combination with spacing-strips for use where wider spacing is required, an adhesive layer on the back of said letters and spacing-pieces, and a resist on said spacing-pieces.

In witness whereof I have hereunto signed myname, this 10th day of April, 1906, in the presence of two subscribing Witnesses.

ERNEST GEORGE MITCHELL.
